Specification of Letters Patent.

` Application tiled February 20, 1912.k Serial No. 678,913.

T 'o all whom t may concern:

Beit known that L-EDMUND H. LUN-KEN, a citizen of the United States,residing at Cincinnati, Ohio, have invented certain new and usefulImprovements in Fireprootl lirdow Construction, of which the following aspecilication. l

My present invention relates to improve ments in tire proof window.construct-ion ofthe type in which weight balanced sliding sashes oftheirreversible type are used.

.metal of 18 gage.

of channell forni with a central partltion 4a,

vAmong the objects of the invent-ion are to providea simple andeconomical construction, one which shall Vbe strong and durable in use,in whichl the sashes maybe readily inserted and removed, and theweight@y and pulleys be readily accessible, and in which adjustment tocause proper iii of the sash may be` readily made.

lVit-h these and other objects in View the invention includes the novelfeatures of construction and arrangement and combination of partshereinafter described and particu larly dened byl-the appended claims.

, A window constructed in accordance with my invention'ff'is illustratedin the acco1npanying drawings in which,

Figure-l is a front elevation of the window'; Fig. 2Ais a perspectiveview `with the sashes and one of the lower cover plates removed; F1g. 31s a perspective View of the rear, and Fi'g.4 a perspective view of thefront of one of t-he cover plates; Fig. 5' is.

a horizontal sect-ion on line 5-5 of Fig. l; Fig. 6 is a sectional plan.illustrating the manner of removing the sash; Fig. T is a verticalsection on line 7 7 of Fig. l; Fig. 8 4is avert-ical section on line 8-8et F ig.

1, Figs. 5 to 8 being for convenience oi illus,- tration drawn on alarger scale than t-he others.

Referring by reference characters to these drawings, the main trame lcomprises a. -top member 2, preferably ot' box like forni, a bottom orsill member 3, and two side meinbers 4, 4, preferably constructed ofsheet The side members are providing two parallel weight. boxes withinwhich move theweights 5 and 5a for the upper and lower sashesrespectively. The open sides of the members 4 vare closed by cap' plates6, which are'a-nged, crimped or folded over the edges of the'vsidemembers 4 as indicated at 6a, to aiorda 'firm connec- -lower sashes8 and 9 are guided.

tion, being preferably-secured thereto by lspot welding.

ianges di' to furnish masonry guides -and 60v means for securing tlyscreens or shutters.. These cap plates are provided with openings 6c and6l for access to the pulleys and' weights, which openings` are coveredby the coverplates 7 upon which'the The cover plates are provided withvertical ribs 7 and 8u which engage with corresponding channels in theedges of the upper and lower sashes, Fig. the cover plates being securedto the cap pistes by' any suitable means, such for example as the screwsindicated at l0, which engage with the threaded holes provided in bars10a. In order to enable the insertion or 7 5 removal'of the sashes ortheir adjustment when desired the cover plates are divided horizontallyon a line slight-ly above the top ofA the lower sash when said lowersash is closed such line of 'vision being clearly indicated 80 atl2 inFigs. 3 and 4, and the cover plates are provided with a plurality lottransversely arranged filling strips or bars as indicated at ll, held inplace by the screws l0 and some of which may be removed or more added as85 circumstances may require. When the sashes are pushed clear to thetop of the window and one of the lower cover plate sections removed,which enables the sash, when.

lowered, to be crowded sufficiently to o'ne' 90 side to enableit `toclear the flanges 6a of the.

cap plates upon the/ opposite. side, as yindicated in Fig. 6, then, ofcourse, the sashI may be readily removed. In the replacement of the sasha reverse operation takes 95' place, and after the sash has been putback, into position and shoved vto the top ofl the window, the npper endof the cover plate section is and sliding it up between the lower end otthe sash and the cap plate at an angle and then forcing it back intoposit-ion to be fastened by the screws. lt is thus evident thatwithout-the two part or sectional adjustable cover plates the insertionand removal of the sashes would be impossible, as there` would not besufficient side play for the sashes to clear the tiange '6a. The illin gstrips l1 are placed transversely so as to give upper and as clearlyVshown in l pnt into place by engaging the progections af carried by theupper sections support to the entire width ot the cover plates.

The side members 4 are also preferably provided with flanges formed byangle irons as indicated at. 13, secured vin-place by spot weldings andforming wind breaks.

`Referring 'more particularly to Fig. 8, it will be clear that thesill 3is provided with and upwardly extending llange 3a which engages achannel formed onthe lower edge of the sash. In order to drain away anyleakage or condensation from the sash, I provide a drain tube lllb whichleads from the depressed portion 14a on the inside of the llange or rib3 to the 'outside of the sill.

. The `sill is' also provided with an inwardly projecting :flange 14:,under which the stool of the sill is placed when attaching the trim.

Thev upper cross member 2 is provided with a flange or rib 2a, alsowedge shape in cross section, which cooperates with the upper edge ofthe sash to form a tight joint in the same manner described inconnection with the sill and lower sash.

I claim as my invention:

l. In a fire proof Window construction, a main rameincluding sidemembers of channel' form providing weight boxes, channel I shaped capplates secured to the edge of the side members and having openings lorac cess to the pulleys and weights,iipper and lower removable coverplates secured to said cap plates and having guides for sliding sashesand transversely arranged spacing strips interposed between the cap andcover plates, substantially as described.

2. In lire proof window construction, a main ranie'ineluding sidemembersof channel form rovided with weight -boxe's,.chan nel'shapev capplates, the legs-of which are secured tothe outer edges ot' theside members forming projecting flanges, openings in the cap platesA for accessto theweights and pulleys, and upper and lower cover plates removablysecured betweenr the projecting -flanges ol' the cap plates, said coverplates having guides for the sashes.

3. In `tire proof Window construction, a main frame including sidemembers of channel form provided with weight boxes, channel shaped capplates, the legs ol? whichl are secured to the outer edges of the sidemem-l` y bers forming projecting flanges, openings in the cap plates'tor access to the weights and pulleys. and upper and lower adjustablecover pla tes removably secured between the projecting flanges ol thecap plates, said' cover plates having guides for the sashes.

l. In tire proof window construction, a main traine including sidemembers ot chalinel torni provided with weight boxes, channel shaped capplates the legs of which are secured to the outer edges of the sidemembers forming projecting flanges, openings in the cap plates foraccess to the weights and pulleys, and upper and lower adjustable coverplates removably secured between the lprojecting flanges of the capplates, and having guides for the sashes, the lower cover plates beinglonger than the up-` per vcover plates.

5. In tire proof window construction,y a main frame including sidemembers of channel 'form provided with weight boxes, cliannel shaped capplates the legs of which are secured to the outer edges ofthe sideineinbers forming projecting flanges, openings in the cap plates toraccess to the weights and pulleys, and upper and lower adjustable coverplates removably secured between the projecting flanges of `the capplates, and having guides for the sashes, the lower cover plates beinglonger than the upper cover plates, said upper andlower cover plateshaving interlocking ends.

6. In tire proof window construction, a main frame including sidemembers of channel form provided with weight boxes, channel shaped capplates the legs of which are secured to the outer edges of the sideniembers forming projecting llanges, openings in the cap plates'foraccess to the weights and pnflleys, `an(`l upper and lower adjustablecover plates removably secured between the projecting tlanges of thecapA plates, and hav- .ing guides for the saslies, the lower coverplates being longer than the upper cover plates, and having spacing'vstrips interposed between the cap and cover plates, substantially asdescribed.

In testimony whereof, I atlix my signaturev in present-.e of twowitnesses.
